SPECIFICATION forming part of Letters Patent No. 263,459, dated August 29, 1882.

Application filed April 17, 1882. (Modeld To all whom it may concern:

] type-basket, or thereabout, when resting at its Be it known that I, CHARLES J. BAKER, of lower edge on the top A, and having a verti- Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Aligner for Type-Writers, of which the followin g is a full, clear, and exact description.

This invention consists of a gage constructed and arranged for temporary attachment to the top of a type-writer, so as to occupy a position in such relation to the point where the type take effect on the paper in operation that the type maybe successively raised up to said point and accurately and uniformly aligned in adj usting them, the said gage being essentially a bar of metal bridging over the type-basket and resting on the type-writer case, with an opening at the type-center, in which slides for the type, also having openings and being suitably cross lined, are fitted to adjust the type by, all as hereinafter more fully described.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of part of the top ofa type-writer, showing the said improved aligner attached. Fig. 2 is a plan view of the alignerinverted. Fig.Sisaperspeetiveviewof the aligner in upright position, and with a gage employed for settin git. Fig. 4 is a plan view-of one of the slides employed in the bar and having the lines by which to align the type for adjustment. Fig. 5 is a plan View of the same inverted. Fig. 6 is a perspective View of a section of the aligner, showing the transparent cover to the slide sometimes used.

A represents the top of the type-writer case, B the type-basket, and 0 some of the typelevers. Over the basket is placed the aligner, consisting of a small light bar of brass or other approved metal, with arched ends E, broad feet F, and straight part D between the ends, with a broadened center, G, said bar being temporarily attached to the top A of the typewriter by hook-headed bolts H and thumbnuts I, and having stud-points M in the bottom of the feet to aid in properly placing it when applying it for use, and to register it for subsequent use.

J represents a gage with which to set the bar, said gage consisting of a small plate curved sidewise to correspond with the margin of the cal notch, K, square to the lower edge, the said notch being not quite as wide as the bar, and the latter having a notch, L, each side for guides to the edges of the notched plate J. The said plate J being placed on the said aligner, as shown, will test the vertical adjustment of the said aligner and aid in correcting it if inaccurate. At the same time the adjustment of the aligner parallel with the carriage-rod of the machine (not shown) will be made with the aid of any suitable measure or straight rod or bar-gage by measuring the distance from one to the other at each end of the said aligner. When the positions for the feet F of the aligner are thus correctly ascertained in the first place the points M will be pressed into the surface of the top A of the case of the type-writer for a register by which to subsequently apply the aligner from time to time, and the hook-headed bolts H will be shifted along the slots N in feet F, suitably for hooking through slots in the top A and under said top, as is common in such fastenings, to be secured by nuts I to clamp the attachment fast. The gage J will be useful to test the aligner from time to time, when subsequently applied, for certainty as to its accuracy; but if the aligner be permanently fixed the gage J should not be required.

The center G has an opening, 0, through it, over which the little gage-plate slides P are inserted in a wide dovetail groove, Q, against the ledge It, or extending entirely across center piece, G, and being secured by screws a, one of which may have part ofits head cut away, as in Fig. 6, to allow the slide to be entered and removed without taking out said screw. These slides P have small holesS and Tthrough them, also the cross center lines, V and W, Fig. 4, the openings being for the type to enter, and the center lines being to align them from. Two or more of these plates 1? will be used, accordio g to the different types used, as single-space and double-space type.

In using this device each type-lever, as it is brought up, if it does not register with the therewith. In the operation of the machine when, by the wear of the machine, the type hole, is bentinto position until it does register the aligner is removed, and is only replaced do not properly register with the printingpoint.

In some cases I propose to employ a transparent cover, I), Fig". 6, of glass or other approved material, to the opening; or openings of these plates P, said cover being fitted in a dovetail groove in the top of the slide, or otherwise suitably attached, said cover being used for the purpose of preventing the smaller letters from coming through.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a type-writer, of the aligner-bar, substantially as herein described, and a gage-plate, l, as set forth.

2. The aligner-bar D E F G and clamp-. screws I1 I, in combination with a type-writer, substantially as specified.

3. The aligner-bar 1) E F G, clamp-screws II I, and stud-points M, in combination with a l type-writer, substantially as specified. I 4. The combination of a transparent cover, I), with the adjusting-slide P of the aligner for t; pe-wiiters, substantially as herein shown and described.

5. The combination, in an aligner for typewriters, of an aligner-bar, I) E F G, adjustingg'age slide 1 and binding-screws a, substantially as described.

(5. The combination of gage J, aligner-bar D E F G, and clamp-screws II I with a type writer, substantially as specified.
